Study type | Interventional |
This multicenter, prospective, interventional study aims to include 2000 gastroscopic procedures and investigate the relationship between procedure time and lesion detection rate in tertiary endoscopic centers in China. At the first stage, the researchers observe the actual procedure time of gastroscopies without affecting the natural behavior of endoscopists. At the second stage, a minimal time limit will be set for each procedure based on the observational results of the first stage. The primary study outcome is focal lesion detection rate. Secondary outcomes include detection rate of early upper GI cancer, biopsy rate and adverse event rate.
